High temperature and high pressure solenoid valve

High Temperature and High Pressure Solenoid Valve Models: GWDRY / YSE / YSE-A / YSI / YSP High temperature, high pressure, and ultra-high pressure solenoid valves are categories of solenoid valves specifically designed for extreme operating conditions. They are used for high-temperature media, high system pressure, and extreme pressure environments, and are widely applied in fields such as hot oil systems, chemical reactions, hydraulics, and testing equipment. The valve body of high temperature solenoid valves is made of stainless steel or heat-resistant alloy steel, with seals made of PTFE or metal hard seal, and is equipped with a long-neck heat dissipation structure to prevent coil overheating and damage. High pressure solenoid valves generally refer to products with operating pressures between 10MPa and 100MPa. The pilot-operated structure is more common, using a pilot valve to control the opening and closing of the main valve, achieving high-pressure actuation with small electromagnetic force. The valve core must be hardened to resist erosion. Ultra-high pressure solenoid valves are suitable for extreme operating conditions with working pressures of 40MPa or even up to 70MPa. They are commonly found in waterjet cutting, high-pressure test benches, and deep-sea equipment. Due to structural limitations on electromagnetic force, ultra-high pressure solenoid valves are mostly normally closed type with two-stage or three-stage pilot-operated designs, and must also be equipped with special explosion-proof coils to ensure safety.
